A U.S. company recently launched a wearable Smart Tap Strap, which is placed on the finger and allows easy typing even when the phone or computer keyboard is not in use.

The user must use Bluetooth to connect the fingertips to the computer or smart device before use. The built-in sensor can capture the different actions of the user's finger, convert the signal into corresponding numbers or letters, and input the computer or smart device.

The development of wearable smart technology will make people's lives and work more convenient.
